Although risky decision-making has been posited to contribute to the maladaptive behavior of individuals with psychopathic tendencies, the performance of psychopathic groups on a common task of risky decision-making, the Iowa Gambling Task (IGT; Bechara, Damasio, Damasio, & Anderson, 1994), has been equivocal. Different aspects of psychopathy (personality traits, antisocial deviance) and/or moderating variables may help to explain these inconsistent findings. In a sample of college students (N = 129, age 18–27), we examined the relationship between primary and secondary psychopathic (...) features and IGT performance. A measure of impulsivity was included to investigate its potential as a moderator. In a joint model including main effects and interactions between primary psychopathy, secondary psychopathy and impulsivity, only secondary psychopathy was significantly related to risky IGT performance, and this effect was not moderated by the other variables. This finding supports the growing literature suggesting that secondary psychopathy is a better predictor of decision-making problems than the primary psychopathic personality traits of lack of empathy and remorselessness.

Ludwig Wittgenstein (1889-1951) was an extraordinarily original thinker, whose influence on twentieth-century thinking far outside the bounds of philosophy alone. In this engaging Introduction, A.C. Grayling makes Wittgenstein's thought accessible to the general reader by explaining the nature and impact of Wittgenstein's views. He describes both his early and later philosophy, the differences and connections between them, and gives a fresh assessment of Wittgenstein's continuing influence on contemporary thought.

Bertrand Russell (1872-1970) is one of the most famous and important philosophers of the twentieth century. In this account of his life and work A.C. Grayling introduces both his technical contributions to logic and philosophy, and his wide-ranging views on education, politics, war, andsexual morality. Russell is credited with being one of the prime movers of Analytic Philosophy, and with having played a part in the revolution in social attitudes witnessed throughout the twentieth-century world. This introduction gives a clear survey (...) of Russell's achievements across their wholerange. (shrink)

In mathematics, the deductive method reigns. Without proof, a claim remains unsolved, a mere conjecture, not something that can be simply assumed; when a proof is found, the problem is solved, it turns into a “result,” something that can be relied on. So mathematicians think. But is there more to mathematical justification than proof? -/- The answer is an emphatic yes, as I explain in this article. I argue that non-deductive justification is in fact pervasive in mathematics, and that it (...) is in good epistemic standing. (shrink)

The 1981 Dahlem conference was a catalyst for contemporary evolutionary developmental biology (Evo-devo). This introductory chapter rehearses some of the details of the history surrounding the original conference and its associated edited volume, explicates the philosophical problem of conceptual change that provided the rationale for a workshop devoted to evaluating the epistemic revisions and transformations that occurred in the interim, explores conceptual change with respect to the concept of evolutionary novelty, and highlights some of the themes and patterns in the (...) different contributions to the present volume, Conceptual Change in Biology: Scientific and Philosophical Perspectives on Evolution and Development.

Over 300 years ago the father of microscopy, Antonie van Leeuwenhoek, observed dried rotifers “coming back to life” upon rehydration. Since then, scientists have been fascinated by the enduring mystery of how certain organisms survive losing essentially drying out completely. Historically sugars, such as the disaccharide trehalose, have been viewed as major functional mediators of desiccation tolerance. However, some desiccation tolerant organisms do not produce this sugar, hinting that additional mediators, and potentially novel mechanisms exist. It has become apparent (...) that a common theme among such organisms is the production and use of intrinsically disordered proteins to mediate survival in this dry state. However, the basic biology of these proteins – which unlike globular proteins lack persistent three-dimensional structure – is poorly understood, as are the functional mechanisms utilized by these enigmatic proteins that allow them to mediate desiccation tolerance. We purpose that probing the biochemical and biophysical nature of stress-related IDPs will provide mechanistic insights into these fascinating proteins. Remarkably, organisms from every kingdom of life can survive losing nearly all their intracellular water. A hallmark of desiccation tolerance is the use of intrinsically disordered proteins, but how IDPs contribute to tolerance is poorly understood. Here, we discuss possible mechanisms and avenues for studying these enigmatic proteins. (shrink)

'The unconsidered life is not worth living' - Socrates. Thinking about life, what it means and what it holds in store does not have to be a despondent experience, but rather can be enlightening and uplifting. A life truly worth living is one that is informed and considered so a degree of philosophical insight into the inevitabilities of the human condition is inherently important and such an approach will help us to deal with real personal dilemmas. This book is an (...) accessible, lively and thought-provoking series of linked commentaries, based on A. C. Grayling's 'The Last Word' column in the Guardian. Its aim is not to persuade readers to accept one particular philosophical point of view or theory, but to help us consider the wonderful range of insights which can be drawn from an immeasurably rich history of philosophical thought. Concepts covered include courage, love, betrayal, ambition, cruelty, wisdom, passion, beauty and death. This will be a wonderfully stimulating read and act as an invaluable guide as to what is truly important in living life, whether facing success, failure, justice, wrong, love, loss or any of the other profound experience life throws out.

Consisting of eleven extended essays, specially commissioned for this volume from leading philosophers, the book surveys all of the major areas of philosophy and offers an accessible but sophisticated guide to the main debates. An extended introduction provides general context and explains how the different subjects are related. The first part of the book deals with the foundations of philosophical inquiry: epistemology, philosophical logic, (...) methodology, metaphysics, and the philosophy of mind. The second part offers historical chapters, two on ancient philosophy and two on modern philosophy. Finally, two chapters deal with questions of value, ethics and aesthetics. Each chapter has a full bibliography. The contributors include Bernard Williams, Roger Scruton, Martin Davies, David Wiggins, Christopher Janaway, David Papineau, and Mark Sainsbury. Designed to be as useful to the third-year student as to the beginner, this exciting new text will give each reader a unique sense of involvement in philosophy as it is practiced today. (shrink)

In this benchmark five-volume study, originally published between 1922 and 1955, Surendranath Dasgupta examines the principal schools of thought that define Indian philosophy. A unifying force greater than art, literature, religion, or science, Professor Dasgupta describes philosophy as the most important achievement of Indian thought, arguing that an understanding of its history is necessary to appreciate the significance and potentialities of India's complex culture. Volume I offers an examination of the Vedas and the Brahmanas, the earlier Upanisads, and the six (...) systems of Indian philosophy. (shrink)

"A distinctive voice somewhere between Mark Twain and Michel Montaigne" is how Psychology Today described A.C. Grayling. In Life, Sex, and Ideas: The Good Life Without God, readers have the pleasure of hearing this distinctive voice address some of the most serious topics in philosophy--and in our daily lives--including reflections on guns, anger, conflict, war; monsters, madness, decay; liberty, justice, utopia; suicide, loss, and remembrance. A civilized society, says Grayling, is one which never ceases having a discussion with itself about (...) what human life should best be. In this book, Grayling adds to this discussion a series of short informal essays about ethics, ideas, and culture. A recurring theme is religion, of which he writes "there is no greater social evil." He argues, for instance, that liberal education is better than religion for inculcating moral values. "Education in literature, history, and appreciation of the arts," he says, "opens the possibility for us to live more reflectively and knowledgeably, especially about the nature and variety of human experience. That in turn increases our capacity for understanding others better, so that we can treat them with respect and sympathy, however different their outlook on life." Thought provoking rather than definitive, these essays don't tell readers what to think, but only note what has been thought about how it is best to live. A person who does not think about life, the author reminds us, is like a stranger mapless in a foreign land. These brief and suggestive essays offer us the outlines of a map, with avenues of thought that are a pleasure to wander down. (shrink)

The Compactness Theorem The compactness theorem is a fundamental theorem for the model theory of classical propositional and first-order logic. As well as having importance in several areas of mathematics, such as algebra and combinatorics, it also helps to pinpoint the strength of these logics, which are the standard ones used in mathematics and arguably … Continue reading Compactness →.

The main object of this impressive study is to lay the groundwork, in contemporary terms, for a systematic and philosophically respectable "apology for poetry." The author finds that most of the so-called New Critics agree in rejecting both the "sugar-coated pill" and "l'art pour l'art" views of poetry; their efforts to formulate a workable third view form the basis for his elaboration of the requirements of an acceptable theory, one which will accord with--and do justice to--the unique and irreducible (...) aesthetic experience to which poetry gives rise. The details of such a theory, unfortunately, are never made entirely clear, owing in part to the diverse and often conflicting demands which must be met, but its main points are as follows: poems, though mainly self-contained, their meanings determined contextually rather than referentially, yet "reveal life," "illuminate human experience"; in poetic creation, though the poet's intentions somehow control the outcome, yet the language of the evolving poem itself determines its own final nature; and poetry, though it neither merely instructs or informs nor merely pleases, yet does provide a kind of "truth" and does produce an experience in some sense pleasurable. The strength of Mr. Krieger's study lies in the clarity and force with which he states the various issues, and in the scholarly care with which he examines the views of individual critics. The book, however, lacks tight organization and sustained, clearly directed argumentation, and its final outcome is rather inconclusive.--V. C. C. (shrink)

Many things have passed as money: salt in Abyssinia, tea-bricks in Asia, sugar in the West Indies, barrels of oil in Texas … and metals everywhere. The list seems endless. However, as transactions increased, wealth accumulated, and states levied taxes, such proto-moneys moved from the simple “double coincidence of wants” into more rational and complex forms. They catered for a market or hierarchy of markets. “Money,” said Carl Menger, “is not a political invention.”.

Logical monism is the claim that there is a single correct logic, the 'one true logic' of our title. The view has evident appeal, as it reflects assumptions made in ordinary reasoning as well as in mathematics, the sciences, and the law. In all these spheres, we tend to believe that there aredeterminate facts about the validity of arguments. Despite its evident appeal, however, logical monism must meet two challenges. The first is the challenge from logical pluralism, according to which (...) there is more than one correct logic. The second challenge is to determine which form of logicalmonism is the correct one. One True Logic is the first monograph to explicitly articulate a version of logical monism and defend it against the first challenge. It provides a critical overview of the monism vs pluralism debate and argues for the former. It also responds to the second challenge by defending a particularmonism, based on a highly infinitary logic. It breaks new ground on a number of fronts and unifies disparate discussions in the philosophical and logical literature. In particular, it generalises the Tarski-Sher criterion of logicality, provides a novel defence of this generalisation, offers a clearnew argument for the logicality of infinitary logic and replies to recent pluralist arguments.
